AMD Releases UVD Video Decode Support For R600 GPUs

[chrisr]

XBMC is "simple"?

xbmc requires it. I'm not sure off hand what other apps use it.

I'm sure that somewhere there are 5 lines of (kernel?) code that could return "1" if frame-based output is available, and "0" if it isn't.

I'm sure that somewhere there are 5 lines of (kernel?) code that could return "1" if frame-based output is available, and "0" if it isn't.

I'm not sure what you are asking. Whether the driver supports field decode or not is determined by the radeon vdpau driver in mesa. This is the relevant mesa patch:

http://cgit.freedesktop.org/mesa/mesa/commit/?id=80771e47b6c1e47ab55f17311e1d4e227a9eb3d8

it returns 1 if field based decode is supported or 0 if not. As you can see from the patch it returns 1 if the asic is newer than RV770. And before someone asks, RV790 is just a faster clocked RV770 so it's treated the same as RV770 from a code perspective.

Has anybody here (except for the Devs) got it working?

Working here with HD 2600 XT and HD 4850 using the modified kernel, the UVD firmwares and the latest update from Oibaf. Tested with (s)mplayer and Flash. XBMC made the 2600 crash when I started a movie, the 4850 worked just fine.

Mixed success with patched 3.16.1 and HD 4890

I've grabbed the 6 patches from the dri-devel mailing list, and applied them to my 3.16.1 kernel. (They apply without any real difficulty). I've also grabbed the RV770_uvd.bin firmware file and included it in my initramfs.img. The end results are definitely encouraging, but aren't quite there yet:

And then there's the playback test...

The Good News is that both "mpv --hwdec=vdpau --vo=vdpau <file>" and "mpv --hwdec=vdpau --vo=opengl <file>" behave identically ! (I am using Fedora 20's standard Mesa 10.1.5 RPMs here, which work fine with my HD4670 AGP in this same test). In other words:

Trying to use hardware decoding.
Selected video codec: H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 [lavc:h264]
Selected audio codec: AAC (Advanced Audio Coding) [lavc:aac]
AO: [pulse] 48000Hz stereo 2ch float
VO: [opengl] 1280x544 => 1280x544 vdpau
AV: 00:00:03 / 00:02:27 (2%) A-V:  0.000

This suggests to me that the UVD 2.1 block does indeed support field-based output . Unfortunately, the decoding is not quite right. In both cases, (i.e. --vo=vdpau and --vo=opengl) it is as if not all of the horizontal lines that make up the picture are being displayed in the correct order - although the correct image is still discernible through the fuzz.

But this is still a valiant first attempt!

Not sure if that is normal... But why don't you try some agd5f kernel tree, one of them have all patches there. You can better help testing that i think

Yeah, I think that's ok. I noticed that when Christian first got it working; extending or adding a delay in that function fixed it. I'll see if I can dig up a patch.

In both cases, (i.e. --vo=vdpau and --vo=opengl) it is as if not all of the horizontal lines that make up the picture are being displayed in the correct order - although the correct image is still discernible through the fuzz.

Sorry, to disappoint you, but it appears UVD 2.1 does not support field based decode. I just tested it on my rv770 and it works fine, but only if you apply this mesa patch:

http://cgit.freedesktop.org/mesa/mesa/commit/?id=80771e47b6c1e47ab55f17311e1d4e227a9eb3d8

The corruption you are seeing is due to the lack of field based decode.

Thanks

Thank you to the team at AMD for continuing to support my laptop.

Confused - because the &quot;no interop&quot; case is affected by this.

My assumption was based on the fact that I saw identical corruption, regardless of whether I was using VDPAU/OpenGL interop or not...

Mesa 10.4.0-devel still advertises GL_NV_vdpau_interop for RV790

I just tested it on my rv770 and it works fine, but only if you apply this mesa patch:

I have compiled the very latest Mesa from git for my HD4890, and have copied the libvdpau_r600.so.1.0.0 object into my /usr/lib64/vdpau directory. When I repeat the "mpv" test now, I get successful playback with "--hwdec=vdpau --vo=vdpau", and a core dump with "--hwdec=vdpau --vo=opengl".

I also notice that glxinfo is advertising the GL_NV_vdpau_interop extension:

I can't claim to understand exactly what is supposed to be happening here, but isn't the current implementation of GL_NV_vdpau_interop dependent on field-based output? And therefore broken for <= RV770?
